Uses Cancer causing product
Nothing was mentioned in the description of the string on line, before we purchased it, but on delivery there was a note on the label that a product used (presumably the dye?) has been found, in the USA, to cause cancer. We were not prepared to take the risk and Amazon gave us a full refund. Maybe, the product should be withdrawn from sale?

This twine does exactly what nylon string is supposed to do. It’s strong for the size, holds tension without stretching, and doesn’t fuzz or fray during use. The thickness is consistent along the length, which matters if you’re tying knots that need to stay put. Cuts cleanly, knots easily, and doesn’t slip once set. The bright white color is useful when visibility matters for gardening, bundling, or layout lines. The spool feeds smoothly without tangling or collapsing halfway through. Nothing fancy, no gimmicks, just reliable material that performs predictably. If you need dependable string rather than decorative twine, this is the correct choice.

Orange leveling line. Good and sturdy. Love the color so people don't trip over it when im laying out

This is pretty good string. It is strong enough to pull on without breaking or stretching. The high visibility color makes it stand out to enough to avoid getting wrapped up in it.

Good nylon string line. Good value and quality. Can be pulled as tight as you need for construction work.
